GUS-QS8B-00-40R2-J Description

The GUS-QS8B-00-40R2-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 40.2Ω resistance and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). The device operates within a wide temperature range of 70°C to 125°C, ensuring stability in demanding environments. Its ±250ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for circuits requiring consistent performance under thermal and electrical stress. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
